In Media3 there is no class/mechanism equivalent of a MediaSessionManager?
If I want my app to control the media session that another app is running, the only way is to convert android.media.session.MediaSession.Token (obtained by the system MediaSessionManager) to MediaSessionCompat.Token then to convert it again to androidx.media3.session.Token? Or did I miss something?

This is more of less correct when going from a platform android.media.session.MediaSession.Token to a media3 session token.

There is already a method to convert the MediaSessionCompat.Token to the media3 token:

public static ListenableFuture<SessionToken> createSessionToken(

Would it help to have a similar method converting android.media.session.MediaSession.Token to a media3 token?

Not sure if relevant to your use case, but it's also possible to directly query all existing media3 sessions associated with a service using this method:

public static ImmutableSet<SessionToken> getAllServiceTokens(Context context) {

Note that this list doesn't include sessions that are not associated to a service (MediaSessionService or MediaLibraryService or MediaBrowserServiceCompat).

If the idea of the media3 library is to progressively phase out the need of the other older media support library, I think it would be good to have a method to directly convert android.media.session.MediaSession.Token to a media3 session token. This way there wouldn't be a need to have a direct dependency to both libraries from our app.

I saw the getAllServiceTokens method but it's not clear to me how to distinguish which token is the one currently active, and like you mentioned we might be missing some sessions in that case. We are also running into SecurityExceptions when trying to create MediaControllers from these tokens.

To explain better our use case, we have a bluetooth companion app, and our users are able to control music played on the Android phone, directly from the watches. Our Android app forwards the media session information from Android to the watches and the inverse is true for the commands (play/pause/skip etc.). We aim to have an implementation that works with as many Android music/media applications as possible.

Agree, I'll convert this to an enhancement.

I saw the getAllServiceTokens method but it's not clear to me how to distinguish which token is the one currently active, and like you mentioned we might be missing some sessions in that case.

That's interesting. I wonder if we need the equivalent of MediaSessionManager.getActiveSessions() that returns an ordered list with the most relevant session listed first. @marcbaechinger What's your take on this?

We are also running into SecurityExceptions when trying to create MediaControllers from these tokens.

Isn't this expected if you don't have permission to access these sessions?

We have permissions to access notifications and we can trigger theirs actions. Controlling any app through the session tokens retrieved from the MediaSessionManager seems to be working fine.

This avoids that apps have to depend on the legacy compat support
library when they want to make this conversion.

Also add a version to both helper methods that takes a Looper to
give apps the option to use an existing Looper, which should be
much faster than spinning up a new thread for every method call.

Added new method to check if codec just functionally supports a format.
Changed getDecoderInfosSortedByFormatSupport to use new function to

their preferred position in the sorted list.

Unit tests included
-Two MediaCodecVideoRenderer tests that verify hw vs sw does not have an
effect on sort of the decoder list, it is only based on functional

* Do not require package visibility when connecting to a Media3 session

When we currently call SessionToken.createSessionToken with a legacy
token, we call the package manager to get the process UID. This
requires visiblity to the target package, which may not be available
unless the target runs a service known to the controller app.

However, when connecting to a Media3, this UID doesn't have to be
known, so we can move the call closer to where it's needed to
avoid the unncessary visibility check.

In addition, a legacy session may reply with unknown result code
to the session token request, which we should handle as well.

One of the constructor can be removed since it was only used from
a test.

* Add `set -eu` to all shell scripts

These flags ensure that any errors cause the script to exit (instead of
just carrying on) (`-e`) and that any unrecognised substitution variables
cause an error instead of silently resolving to an empty string (`-u`).

Issues like Issue: google/ExoPlayer#10791 should be more quickly resolved with
`set -e` because the script will clearly fail with an error like
`make: command not found` which would give the user a clear pointer
towards the cause of the problem.

* Do not require package visibility when obtaining SessionTokens

The only reason this is required at the moment is to set the
process UID field in the token, that is supposed to make it easier
for controller apps to identify the session. However, if this
visibility is not provided, it shouldn't stop us from creating
the controller for this session.

Also docuement more clearly what UID means in this context.

* Add `DefaultExtractorsFactory.setTsSubtitleFormats`

ExoPlayer is unable to detect the presence of subtitle tracks in some
MPEG-TS files that don't fully declare them. It's possible for a
developer to provide the list instead, but doing so is quite awkward
without this helper method. This is consistent for how
`DefaultExtractorsFactory` allows other aspects of the delegate
`Extractor` implementations to be customised.

* Load bitmaps for `MediaSessionCompat.QueueItem`.

When receiving the `onTimelineChanged` callback, we convert the timeline to the list of `QueueItem`s, where decoding a bitmap is needed for building each of the `QueueItem`s. The strategy is similar to what we did in <unknown commit> for list of `MediaBrowserCompat.MediaItem` - set the queue item list until the bitmaps decoding for all the `MediaItem`s are completed.

* Call future listener on the same handler that created the controller

The direct executor is not the proper way to determine on what thread to run the
`Future.Listener` and the `MediaControllerCreationListener` because the listener
may call the controller passed as argument which must happen on the same thread
that built the controller. This change makes sure this is the case.

* Exclude tracks from `PlayerInfo` if not changed

This change includes a change in the `IMediaController.aidl` file and needs
to provide backwards compatibility for when a client connects that is of an older or
newer version of the current service implementation.

This CL proposes to create a new AIDL method `onPlayerInfoChangedWithExtensions`
that is easier to extend in the future because it does use an `Bundle` rather than
primitives. A `Bundle` can be changed in a backward/forwards compatible way
in case we need further changes.

The compatibility handling is provided in `MediaSessionStub` and `MediaControllerStub`. The approach is not based on specific AIDL/Binder features but implemented fully in application code.

* Handle the bitmap loading result with applicationHandler

Before this change, the bitmap loading result with mainHandler, in which we set the metadata to `MediaSessionCompat`. However, the `MediaSessionCompat` is not thread safe, all calls should be made from the same thread. In the other calls to `MediaSessionCompat`, we ensure that they are on the application thread (which may be or may not be main thread), so we should do the same for `setMetadata` when bitmap arrives.

Also removes a comment in `DefaultMediaNotificationProvider` as bitmap request caching is already moved to CacheBitmapLoader.

* Remove flakiness from DefaultAnalyticsCollectorTest

Our FakeClock generally makes sure that playback tests are fully
deterministic. However, this fails if the test uses blocking waits
with clock.onThreadBlocked and where relevant Handlers are created
without using the clock.

To fix the flakiness, we can make the following adjustments:
 - Use TestExoPlayerBuilder instead of legacy ExoPlayerTestRunner
   to avoid onThreadBlocked calls. This also makes the tests more
   readable.
 - Use clock to create Handler for FakeVideoRenderer and
   FakeAudioRenderer. Ideally, this should be passed through
   RenderersFactory, but it's too disruptive given this is a
   public API.
 - Use clock for MediaSourceList and MediaPeriodQueue update
   handler.

* Ensure messages sent on a dead thread don't block FakeClock execution

FakeClock keeps an internal list of messages to be executed to
ensure deterministic serialization. The next message from the list
is triggered by a separate helper message sent to the real Handler.
However, if the target HandlerThread is no longer alive (e.g. when
it quit itself during the message execution), this helper
message is never executed and the entire message execution chain
is stuck forever.

This can be solved by checking the return values of Hander.post or
Handler.sendMessage, which are false if the message won't be
delivered. If the messages are not delivered, we can unblock the
chain by marking the message as complete and triggering the next
one.

* Use the artist as the subtitle of the legacy media description

The Bluetooth AVRCP service expects the metadata of the item currently
being played to be in sync with the corresponding media description in
the active item of the queue. The comparison expects the metadata values
of `METADATA_KEY_TITLE` and `METADATA_KEY_ARTIST` [1] to be equal to the
`title` and `subtitle` field of the `MediaDescription` [2] of the
corresponding queue item.

Hence we need to populate the media description accordingly to avoid the
BT service to delay the update for two seconds and log an exception.

* Decomission ControllerInfoProxy in favor of ControllerInfo.

This CL makes it possible to create a media3 ControllerInfo in test code, which is needed to test several aspects of a media3-based media app. It does this by exposing a test-only static factory method. This is a hacky low-effort approach; a better solution could be to split ControllerInfo up into a public interface that was exposed to client logic, and that they could extend, and a package-private implementation with internal fields like the callback. That's a much bigger change, however.

goes beyond the repeated implementation pattern in this change.

* Reduce log output for failing bitmap loads

Do not log the exception stack traces raised by the BitmapLoader when a
bitmap fails to load, e.g. when the artwork's URI scheme is not
supported by the SimpleBitmapLoader. The logs are kept in place but only
a single line is printed.

* Stop service when app is terminated while the player is paused

If the service ever has been started but is not in the foreground, the
service would be terminated without calling onDestroy(). This is because
when onStartCommand returns START_STICKY [1], the app takes the
responsibility to stop the service.

Note that this change interrupts the user journey when paused, because the
notification is removed. Apps can implement playback resumption [2] to give
the user an option to resume playback after the service has been terminated.

* Support release in SimpleBasePlayer

This adds support for the release handling. To align with the
established behavior in ExoPlayer, the player can only call
listeners from within the release methods (and not afterwards)
and automatically enforces an IDLE state (without listener call)
in case getters of the player are used after release.

* Replace MediaMetadata folderType by isBrowsable

The folder type has a mix of information about the item. It shows
whether the item is browsable (type != FOLDER_TYPE_NONE) and
which Bluetooth folder type to set for legacy session information.

It's a lot clearer to split this into a boolean isBrowsable and
use the existing mediaType to map back to the bluetooth folder type
where required.

folderType is not marked as deprecated yet as this would be an API
change, which will be done later.

* Clarify and correct allowed multi-threading for some Player methods

Some Player methods like getting the Looper and adding listeners
were always allowed to be called from any thread, but this is
undocumented. This change makes the threading rules of these
methods more explicit.

Removing listeners was never meant to be called from another thread
and we also don't support it safely because final callbacks may
be triggered from the wrong thread. To find potential issues, we
can assert the correct thread when releasing listeners.

Finally, there is a potential race condition when calling addListener
from a different thread at the same time as release, which may lead to
a registered listener that could receive callbacks after the player is
released.

* Forward seek command details to seekTo method in BasePlayer

BasePlayer simplifies implementations by handling all the various
seek methods and forwarding to a single method that can then be
implemented by subclasses. However, this loses the information about
the concrete entry point used for seeking, which is relevant when
the subclass wants to verify or filter by Player.Command. This
can be improved by adding the command as a new parameter. Since
we have to change the method anyway, we can also incorporate the
boolean flag about whether the current item is repeated to avoid
the separate method.

* Allow unset index and position values + remove period index

This simplifies some position tracking needs for an app implementing
SimpleBasePlayer.
 - The period index can always be derived from the media item index
   and the position. So there is no need to set it separately.
 - The media item index can be left unset in the State in case the app
   doesn't care about the value or wants to set it the default start
   index (e.g. while the playlist is still empty where UNSET is
   different from zero).
 - Similarly, we should allow to set the content position (and buffered
   position) to C.TIME_UNSET to let the app ignore it or indicate the
   default position explictly.

* Clarify behavior for out-of-bounds indices and align implementations

Some Player methods operate relative to existing indices in the
playlist (add,remove,move,seek). As these operations may be issued
from a place with a stale playlist (e.g. a controller that sends
a command while the playlist is changing), we have to handle out-
of-bounds indices gracefully. In most cases this is already
documented and implemented correctly. However, some cases are not
documented and the existing player implementations don't handle
these cases consistently (or in some cases not even correctly).

The tunneling callbacks are sent via Handler messages and may be

against a released codec yet.

* Fix recursive loop when registering controller visibility listeners

There are two overloads of this method due to a type 'rename' from
`PlayerControlView.VisibilityListener` to
`PlayerView.ControllerVisibilityListener`. Currently when you call one
overload it passes `null` to the other one (to clear the other listener).
Unfortunately this results in it clearing itself, because it receives
a null call back!

This change tweaks the documentation to clarify that the 'other'
listener is only cleared if you pass a non-null listener in. This solves
the recursive problem, and allows the 'legacy' visibility listener to be
successfully registered.

This fix applies to Android 12 and above.

In this fix, the `MediaSessionService` will try to start in the foreground before the session playback resumes, if ForegroundServiceStartNotAllowedException is thrown, then the app can handle the exception with their customized implementation of MediaSessionService.Listener.onForegroundServiceStartNotAllowedException. If no exception thrown, the a media notification corresponding to paused state will be sent as the consequence of successfully starting in the foreground. And when the player actually resumes, another media notification corresponding to playing state will be sent.

* Make availableCommands known when bundling PlayerInfo

When bundling PlayerInfo, we remove data when the controller is not
allowed to access this data via getters. We also remove data for
performance reasons. In the toBundle() method, it's currently hard to
make the connection between allowed commands and filtering, because
the values are checked at a different place. This can be made more
readable by forwarding the applicable Commands directly.

The only functional fix is to filter the Timeline when sending the
first PlayerInfo after a connecting a controller if the command to
get the Timeline is not available. This also allows us to remove a
path to filter MediaItems from Timelines as it isn't used.

* Extend command GET_CURRENT_MEDIA_ITEM to more methods.

We currently only document it for the getCurrentMediaItem(), but
the command was always meant to cover all information about the
current media item and the position therein.

To correctly hide information for controllers, we need to filter
the Timeline when bundling the PlayerInfo class if only this
command is available.

We stop estimating new position when pausing until we

adds unit tests to cover the different combinatoric cases these
properties being set or unset.

- when the player changes its available commands, a new
  PlaybackStateCompat is sent to the remote media controller to
  advertise the updated PlyabackStateCompat actions.
- when the player changes its available commands, the legacy media
  session flags are sent accoridingly: FLAG_HANDLES_QUEUE_COMMANDS is

* Fix AudioTrackPositionTracker logic for playback speed adjustments

The AudioTrackPositionTracker needs to correct positions by
the speed set on the AudioTrack itself whenever it makes
estimations based on real-time (=the real-time playout
duration is not equal to the media duration played).

This happens for the main playback path already, but not for
the mode in which the position is estimated from the playback
head position and also not in the phase after the track has
been stopped. Both cases are not very noticeable during
normal playback, but become relevant when playing in offload
mode.

* AsynchronousMediaCodecAdapter: surface queueing errors sooner

The AsynchronousMediaCodecAdapter's queuing thread stores any exceptions
raised by MediaCodec and re-throws them on the next call to
queueInputBuffer()/queueSecureInputBuffer(). However, if MediaCodec
raises and error while queueing, it goes into a failed state and does
not announce available input buffers. If there is no input available
input buffer, the MediaCodecRenderer will never call
queueInputBuffer()/queueSecureInputBuffer(), hence playback is stalled.

This change surfaces the queueing error through the adapter's dequeueing
methods.

* Reduce number of calls to AudioTrack.getPlaybackHeadPosition

This call may cause performance overhead in some situations,

change in any meaningful way.

* Skip rendering multiple frames on the same vsync

When rendering frames at a rate higher than the screen refresh rate,
e.g. playing at 8x, the player is releasing multiple frames at the same
release time (nanos) which are then dropped by the platform. The output
buffers are available later and as a result MediaCodec cannot keep up
decoding fast enough.

This change skips releasing multiple video frames on the same vsync
period and proactivelly drops the frame. The frame is counted as skipped
rather than dropped to differentiate with frames dropped due to slow
decoding.

(cherry picked from commit d0cbf0fce84aa73be5eb68935d6a4dd2f2e1dc3d)

* Ensure output format is updated in sync with stream changes.

MediaCodecRenderer currently has two independent paths to trigger
events at stream changes:
 1. Detection of the last output buffer of the old stream to trigger
    onProcessedStreamChange and setting the new output stream offset.
 2. Detection of the first input buffer of the new stream to trigger
    onOutputFormatChanged.
Both events are identical for most media. However, there are two
problematic cases:
  A. (1) happens after (2). This may happen if the declared media
     duration is shorter than the actual last sample timestamp.
  B. (2) is too late and there are output samples between (1) and (2).
     This can happen if the new media outputs samples with a timestamp
     less than the first input timestamp.

This can be made more robust by:
 - Keeping a separate formatQueue for each stream to avoid case A.
 - Force outputting the first format after a stream change to
   avoid case B.

(cherry picked from commit e1d12fc395d9f9edb28755a5b1026e26b378e005)

* Fix some playback parameter signalling problems.

Playback parameter signalling can be quite complex because
 (a) the renderer clock often has a delay before it realizes
     that it doesn't support a previously set speed and
 (b) the speed set on media clock sometimes intentionally
     differs from the one surfaced to the user, e.g. during
     live speed adjustment or when overriding ad playback
     speed to 1.0f.

This change fixes two problems related to this signalling:
 1. When resetting the media clock speed at a period transition,
    we don't currently tell the renderers that this happened.
 2. When a delayed speed change update from the media clock is
    pending and the renderer for this media clock is disabled
    before the change can be handled, the pending update becomes
    stale but it still applied later and overrides any other valid
    speed set in the meantime.

Both edge cases are also covered by extended or new player tests.
